Locus 3.19.0: how to hide blue icons on route waypoints ?

Locus 3.19.0: when creating manually a route, once all the waypoints of the route have been selected on the map and the route is saved, the route is displayed with a blue icon atop of each way point. This feature could be useful to view the position of each way point, but it is also extremely obstructive as the icons hide large areas of the map.

This feature was not there on previous versions of Locus.

I tried to find in the route menus and in the Locus settings a way to hide these icons, with no success.

I tried to hide, then to show the route: the icons are displayed again atop of the way points.

I can't seem to find the solution after upgrading to 3.20.0. Is there any way to hide the waypoints of existing tracks (created between 3.19.0 and 3.20.0) or does the bugfix only affect newly created ones?
